Volume One looks at the causes and consequences of the collapse of the balance of power after 1914. Volume Two examines the emergence of the United States and its impact on international politics in a bipolar world. Volume Three considers the peaceful conclusion of the Cold War. Volume Four looks at the ways theorists of international relations conceptualized the post-Cold War unipolar 'moment' under conditions of globalization. Volume Five traces the rise of the new Europe but explains the continuing weakness of Europe as an international actor. Volume Six examines the claim that the new 21st century is more likely to revolve around the Pacific than the United States or the Atlantic. Volume Seven asks the question: whatever happened to the Third Word? Volume Eight explores the possible sources of new challenges to international order following the brutal termination of the short-lived post-Cold War era on September 11, 2001.
